How to generate meta name="description" on all pages of a website? How to make the site work not from the root, but from a subdirectory?

Sometimes it happens that on some pages of the restored site there is no meta name="description" tag. It can be added manually, but if it is not available on hundreds or thousands of pages, then it will be difficult to do. In order not to think about compiling page descriptions for a long time, you can simply put in this tag the first phrase that appears in the text on this page. Usually it will be relevant.

The opportunity to use regular expressions for searching and replacing in Archivarix CMS may help you with it. Simply copy the following regular expression into the appropriate fields in the Search and Replace tool and start the process.

(</title>)(.*?<p>([^"<]{50,200}\.))

$1
<meta name="description" content="$3">
$2

meta name="description" 

This regular expression creates the <meta name = "description" content = tag immediately after the closing </title>  and adds text from the page starting with the paragraph tag <p> and having a minimum of 20 characters and a maximum of 200 characters and closes the tag with a dot . . The filter rule makes replacements only on those pages where there is no meta name = "description" .

Another example: A restored site can be redone so that it can work from a subdirectory. This may be necessary if you need to host several restored websites on the same domain. 

To begin with, we change all the paths in the site structure by using the Search and Replace URL tool . 

To all URLs from the beginning ^ we add a new path /newsite1

Next, we replace all the addresses inside the pages using regular expressions, be sure to include all the files (js, css, txt, json, xml) in the request:

\b((?:href|src)=['"]?)(/[^/])

$1/newsite1$2

To fix links to images in CSS files, you can use the following regular expression:

(url \ (['"\ s]) (/ [^ /])

Now in the .htaccess file you need to replace the line RewriteRule. /index.php [L] on such a line - RewriteRule. /newsite1/index.php [L]

Your website will work now at domain.com/newsite1
